These functions are intended to be passed to the
xscale.components
or yscale.components
arguments of
highlevel lattice plots. See xscale.components.default
.
xscale.components.logpower
draws tickmarks at the same
locations as the default, but labels them more smartly using
superscripts for the power (using expressions).
xscale.components.fractions
labels the tickmarks as fractions.
xscale.components.log10ticks
puts major tick marks at powers of
10, and minor tickmarks in between.
